Title: Liquid crystal panel
Inventor: SUMIDA SHIROU
IPC: H05F3/02
Filed: 1992-11-18
Abstract: PURPOSE:To prevent the orientation disturbance of liquid crystal due to the application of a high voltage on the periphery of a spacer particle from occurring by using the spacer particle having conductivity larger than that of a liquid crystal layer. CONSTITUTION:A panel is generated so that the distribution density of a nickel plating spacer 10 of means particle diameter of 5.0-7.0mum becomes 100-300/mm<2>. In such a case, a spacer particle having conductivity larger than that of the liquid crystal layer is used. Since a voltage applied to the liquid crystal layer on the periphery of the spacer particle is low as compared with the one applied to the liquid crystal layer in an area to be apart from the spacer particle even when a high DC voltage is impressed between upper and lower transference electrodes, no orientation disturbance on the periphery of the spacer particle occurs. Also, the orientation disturbance on the periphery of the spacer particle can be suppressed in spite of the spacer particle diameter and distribution density in view of principle by using the spacer having conductivity larger than that of the liquid crystal layer.

IPC: G02F1/135
Filed: 1986-12-26
Abstract: PURPOSE:To simplify a driving circuit of a liquid crystal cell, and to easily form a large screen by connecting a display part of a cell structure which has inserted and held a liquid crystal between first and second clads, and a color CRT for emitting light beams of three colors of R, G and B, by an optical fiber, executing a vertical scan by the display part, and executing a horizontal scan by the color CRT. CONSTITUTION:A video signal inputted to a color CRT 1 is converted to optical signals of R, G and B, and scanned to a fluorescent surface. By the color CRT 1, only a scan in the horizontal direction is executed, and each optical signal is led into a display part 2 through an optical fiber from the fluorescent surface. The optical signals which have been led into the display part 2 are propagated, while repeating a total reflection by a boundary surface of the second clad 12 and a core 10, and a boundary surface of the core 10 and the second electrode 9. In this state, when one of the first electrodes 8 of a band shape formed on the first clad 11 is selected, a boundary surface of the second electrode of a part corresponding to the selected first electrode 8 and a liquid crystal 13 becomes a transmission state, and the optical signal is radiated to the outside. In such a way, an operation of a liquid crystal cell becomes binary, and a driving circuit can be simplified remarkably.

When the load of rubber is less than 30pts.wt., the elasticity is reduced, and when it is more than 100pts.wt., the adhesiveness is reduced. When the load of plasticizing material is less than 50pts.wt., said object becomes too hard and when it is more than 200pts.wt., the retention of shape is deteriorated. When the load of filler is less than 100pts.wt., the resistance to chipping of said object is inferior and when it is more than 500pts.wt., the adhesiveness of said object is deteriorated.
